public class GelfLogHandler
extends Handler
implements ErrorReporter

Logging-Handler for GELF (Graylog Extended Logging Format). This Java-Util-Logging Handler creates GELF Messages and posts them using UDP (default) or TCP. Following parameters are supported/needed:

• host (Mandatory): Hostname/IP-Address of the Logstash Host
  • (the host) for UDP, e.g. 127.0.0.1 or some.host.com
  • See docs for more details
• port (Optional): Port, default 12201
• version (Optional): GELF Version 1.0 or 1.1, default 1.0
• originHost (Optional): Originating Hostname, default FQDN Hostname
• extractStackTrace (Optional): Post Stack-Trace to StackTrace field (true/false/throwable reference [0 = throwable, 1 = throwable.cause, -1 = root cause]), default false
• filterStackTrace (Optional): Perform Stack-Trace filtering (true/false), default false
• includeLogMessageParameters (Optional): Include message parameters from the log event (see LogRecord.getParameters(), default true
• includeLocation (Optional): Include source code location, default true
• mdcProfiling (Optional): Perform Profiling (Call-Duration) based on MDC Data. See MDC Profiling, default false
• facility (Optional): Name of the Facility, default gelf-java
• level (Optional): Log-Level, default INFO
• filter (Optional): Class-Name of a Log-Filter, default none
• additionalField.(number) (Optional): Post additional fields. Eg. .GelfLogHandler.additionalField.0=fieldName=Value

The publish(LogRecord) method is thread-safe and may be called by different threads at any time.
